The agency which supplies 26 Iowa hospitals with a vital fluid is prepared for virtually any disaster on New Year’s Eve. The Blood Center of Central Iowa has gone well beyond making sure its computers are Y-2-K compliant and is readying for whatever may happen — which officials hope is nothing.Jackie Cacciatore is spokeswoman for the Des Moines-based blood center, which is setting up communications with hospitals via e-mail and cell phone, in addition to ham radio. She says the center wants to have a plan in place that could deal with any medical situation.She says the biggest concern is having enough donors to handle the everyday needs of the facility — and urges donors to call & schedule appointments either now or through mid-January. The center serves 22 central Iowa counties.
